Approval and Promulgation of Air Quality Implementation Plans; State of Colorado; Revised Transportation Conformity Consultation Process
EPA is proposing approval of a State Implementation Plan (SIP) revision submitted by the State of Colorado on May 11, 2012. The May 11, 2012 submittal addresses updates to Regulation Number 10 ``Criteria for Analysis of Conformity'' of the Colorado SIP including revisions to transportation conformity requirements, transportation conformity criteria and procedures related to interagency consultation, and enforceability of certain transportation related control and mitigation measures. The submittal also removes certain provisions from the SIP so that federal rules will govern conformity of general federal actions. EPA is proposing approval of the submission in accordance with the requirements of section 110 of the Clean Air Act (CAA).
Public Water System Supervision Program Revision for the Commonwealth of Kentucky
Notice is hereby given that the Commonwealth of Kentucky is revising its approved Public Water System Supervision Program. Kentucky has adopted the following rules: Consumer Confidence Report, Ground Water and Long Term 1 Enhanced Surface Water Treatment. The EPA has determined that Kentucky's rules are no less stringent than the corresponding federal regulations. Therefore, the EPA is tentatively approving this revision to the Commonwealth of Kentucky's Public Water System Supervision Program.

Approval and Promulgation of Implementation Plans; Tennessee; Infrastructure Requirements for the 2008 Lead National Ambient Air Quality Standards; Correction
On June 18, 2013, EPA published a final rule approving certain infrastructure requirements of the Clean Air Act (CAA) for Tennessee's State Implementation Plan (SIP) for the 2008 Lead national ambient air quality standards (NAAQS). The CAA requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA, which is commonly referred to as an ``infrastructure'' SIP. Further, in the June 18, 2013, final rule, EPA explained that the Agency was not taking action on the prevention of significant deterioration (PSD) elements of Tennessee's infrastructure SIP, and that action on those infrastructure elements for the 2008 Lead NAAQS would occur in a subsequent action. This action corrects a typographical error in the regulatory language in paragraph (c) of EPA's June 18, 2013, final rule related to the status of EPA's action on these PSD elements for Tennessee's 2008 Lead NAAQS infrastructure SIP.
